CONVEYER Application filed .une 5, 1319. Serial No. 302,009.

To (all 'whom t may concern.' d

Be it known that l, lVILLrAixir C. Frsrinn, a citizen or tho United States, and aresident ot Middlei'gown, in the county oft Middlesex and State of Connecticut, have invented certain new and useful mprovements in Conreyer Belts; and I do hereby declare the following to be a full, clear, and exact description ot the invention, such as will enable others skilled in the art to Which it appertains to make and use the same.

rlhis `invention relates to improvements in conveyer belts and more particularly to such as. are adapted to run over idlers arranged in trough formation and employed for conveying,` material such as coal, grain, and more or less comminuted material, which may be discharged thereon from a chute,the object of my invention being to provide a Woven conveyer belt with a rein forced or thickened central Woven portion which shall be capable ot' effectually Withstanding the impact of the load While being deposited thereon and which shall operate to resist the strain to which the central portion of a conveyer belt is subjected during the travel ot the same, when loaded, over the idlers .ot a conveyer mechanism.

VVith these and other objects in view, the invention consists in certain novel features ot construction and combinations of par s as hereinafter set forth and pointed out in the claim.

ln the accompanyiug` drawings; llinure l is a transverse sectional View illustrating one manner o't Wearing a conveyer belt embodyinn my invention: Figure 2 is e seetional view on the line 2 2 oit Figure l, and Figures R and 4 are views illustrating other ways ot Weaving the thickened central portion ot the belt.

l, 2, represent the longitudinal or Warp threads ot the Ytabric; fl the Wett threads` and 5 the binder threads.

The belt shown in l" i; igures l. and 2 contains the saine number ot plies throughout., but for the purpose oit thickening and thereby reinforcing the intermediate or central portion 6, the number of Wrap threads is increased in each ply as indicated at 3, While in the portions 7, 7, between the thickened central portion 6 and the side portions 8, 8, ot the belt, the number of Warp threads in each ply is less than 'in the central portion 6 vand greater than in the side portions 8. Thus the belt is gradually thickened A`Join the side portions 8 to the central portion 6 and no shoulders or ledges are :termed which would be liable to retain portions or the material and inter-'tere more or less with the satisfactory operation ot the conveyer. i

l'nstead of Weaving the central portion of the belt by increasingthe number of Warp threads in this portion of the belt Without increasing` the number oi plies, I may employ larger Warp threads 9 as indicated in Figure 8, and the Warp threads of the portions Z between the central. portion 6 and the side portions 8, may be sizes intermediH ate the sizes oit the central Warp threads 9 and the warp threads l1 ot the side portions ot the belt. i

ln the form ot the invention shown in ii ure 4: the thickened central portion 6 of th belt is formed by increasing; the number ot plies in this portion of the belt as indicated at 12.

Having fully described my invention what l claim as new and desire to secure by Letters-Patent, is

A Woven eonveyer belt consisting of a pluralityv oit interwoven plies and containino; the saine number ot plies throughout, ez h ply having a maximum amount of warp thread material in its central portion, o less number ot Warp threads in its side portionsAv and a number ot Warp threads in the portions or' the belt between said cen- -tral portions and side portions Which is less WILLIAM C.
